Polymeric flocculants have been widely used. The product form is
In addition to the conventional powder type, in recent years, water-in-oil type polymer flocculants or water-soluble polymer dispersion type polymer flocculants have attracted attention due to their good handling properties, and many proposals have been made and used. . For example, Japanese Patent Publication No. 54-37986 discloses a monomer aqueous solution of 30 to 70% by weight and a hydrophobic organic liquid 70 to 30.
A method for obtaining a water-in-oil type polymer emulsion by emulsifying and dispersing wt% by using a surfactant is disclosed in JP-A-2-1058.
No. 09, a dimethylaminoethyl (meth) acrylate is used with a monomer obtained by quaternizing an aliphatic halide or an aromatic halide having 4 to 10 carbon atoms in an aqueous solution of an inorganic salt that does not dissolve the polymer, and There has been proposed a method of polymerizing in the presence of a dispersant composed of a cationic polymer which can be dissolved in this salt aqueous solution to obtain a water-soluble polymer dispersion type.

In order to use these polymer flocculants for use, the polymer flocculants are usually stored in a tank, but in the powder form, they are usually 0.1 to 5.0% by weight aqueous solution and water in oil. In the case of type polymer emulsion and water-soluble polymer dispersion type, they are stored as undiluted product solutions, respectively. However, when these polymer flocculants are stored for a long period of time, polymer particles are precipitated and re-aggregated, and viscosity changes such as thickening or thinning occur, so that there are problems in stability over time, storage stability and the like. In particular, since the use of water-in-oil type polymer emulsions has increased in recent years, stability over time and storage stability in long-term tank storage have become important.

The function of the polymer emulsion composition of the present invention is as follows.
Due to the action of the inorganic salt, the water-in-oil type polymer emulsion is mixed with the aqueous polymer solution and / or the water-soluble polymer aqueous dispersion to form a polymer emulsion composition having good fluidity and good storage stability. That is, the inorganic salt has the function of uniformly dispersing or not dissolving the polymer in the composition in the form of fine particles, and the polymer particles are finely dispersed in the composition in a uniform manner. Further, the inorganic salt acts to convert the hydrophobic organic liquid in the water-in-oil type polymer emulsion into oil-in-water emulsion particles. Therefore, since the hydrophobic organic liquid becomes emulsion fine particles and mixes between the polymer particles that are uniformly dispersed, sedimentation or aggregation of the polymer particles is prevented, and the composition has good storage stability and good fluidity. It is supposed to be.
